2 ways to increase the swap space

1. By using SAM
   SAM > Disk and File Systems > Swap > Actions
   You can add the Device Swap or File System Swap.
   
2. By Command Line
   Create the logical volume for your secondary swap:
   # lvcreate -L 128 /dev/vg14
   
   NOTE: "-L 128" is the size of desired swap
   
   Verify the logical volume:
   # lvdisplay /dev/vg14/lvol15
   
   Use SAM to declare your new secondary swap or use the command line:
   # swapon /dev/vg14/lvol15
   
   Verify it has been added in "/etc/fstab" when using SAM, or add it manuallywhen using the command line.
   
   Example:
   /dev/vg14/lvol15 . swap defaults 0 0
